tected in temperate South- America. Other instances arc
Camellia, Deutzia, Hydrangea, Viburnum, several Cornea*, and
Houttuynia.
The recent able investigation of the Hongkong Flora by
Major Champion and Mr. Bentham has materially increased
our knowledge of the intimate relationship between the
Floras of China and the eastern parts of India; amongst
many instances, we may select the repaarkable genus of Ferns,
Bowringia*, found in Hongkong and in the Khasia moun-
tains ; Wikstrcemia, a genus of Daphnes; Bucklandia, Enki-
anthus, Henslovia, Scepa, Antide&ma, Benihamla, Gwigtda,
Myrica, and very many others; in fact, there is scarcely a
genus in the yholc Hongkong Flora that is not also Indian.
Euryale ferox, which is wild in the Gangetic delta, and its
found as far westward as Kashmir, is abundant in China; and
Nepenthes phyllamphora, a native of the Khasia mountains,
is also found at Macao, and eastward to the Louisiadc Archi-
pelago.
4, The Siberian type.—This is characteristic of the colder
temperate parts of Asia, and is very fully represented iu the
upper temperate and alpine regions of the Himalaya, de-
scending in the north-western and drier parts of the chain to
very low levels. It approaches, in many respects, to the
South European -vegetation, but is characterized by the pre-
dominance of Fumariacea, PotentitttB, Leguminosa, especially
Hedysarum and Astragale®, of Umbellifera, Lonicera, Arte-
misia, Pedtcufaris, and Boraginea; and by the rarity or total
absence of certain groups or genera .which are especially
abundant in Europe, such as Cistace®, Rosa, Rubus, Trifolium,
Erica, Ferns, and other cryptogams. As the Alps of Central
Asia rise gradually from the elevated tracts of Southern Sibe-
ria, and possess a very similar climate, the increasing elevation
compensating for the diminution of latitude, a very Siberian
